Assemble the illumination

In this section we are assembling the sample illumination. This is for transmission illumination.

For this section you will need:

Tools

1 2.5mm Ball-end Allen key
1 heatgun - If you don't have a heatgun the soldering iron can be used
1 precision wire cutters
1 soldering iron
1 wire strippers

Printed Parts

Printed Tools

1 Lens tool

Consumables

a little solder

Optical Components

1 condenser lens

Electronic Components

1 150 Ohm Resistor - - The exact value will depend on the current rating of your LED.
1 2 pin Du Pont connector female housing
40 mm of Black heatshrink - 4.8mm ID
1 Black pre-crimped Female-Female jumper cable (30 cm)
35 mm of Red heatshrink - 2.4mm ID
1 Red pre-crimped Female-Female jumper cable (30 cm)
1 Warm white 5mm LED

Mechanical Components

Step 1: Solder the LED

If you have purchased a kit you may already have an assembled soldered LED cable

Tun on your soldering iron so it can heat up
Take the LED
Cut the longest leg down to about 5mm long using precision wire cutters
Tin this leg with solder
Take a 150 Ohm Resistor and cut each leg down to about 5mm long. (why?)
Tin both legs with solder
Solder one side of the resistor to the cut leg of the LED.
Cut the other leg of the LED to be the same height as the end of the resistor.
Tin the end of this leg
Take the red and black precrimped jumper cables and cut off one end with wire strippers
Strip about 5mm of cable on each, and tin the cable with wire strippers
Solder the red wire to the leg with the resistor
Solder the black wire to the other leg
Take the red heatshrink and slide it over the red cable up to the LED.
Use a heatgun to shrink the heatshrink
Take the black heatshrink and slide it over both cables up to the LED.
Use a heatgun to shrink the heatshrink

Step 2: Add the connector

Take the DuPont housing
Push both connectors from the LED cable into the connector

Step 3: Mount the dovetail

Place the illumination dovetail onto the stage above the z-actuator of the main body.
Secure in place with two M3x10 cap head screws and 2 M3 Washers (using 2.5mm Ball-end Allen key)

Step 4: Push-fit the lens

Place the condenser lens on the lens tool flat side down
Take the condenser arm and align the opening over the lens
Push down until the lens clicks into place.

Step 5: Add the condenser retaining screw

Place an M3x25mm stainless steel hex bolt through the Illumination thumbscrew
Drop an M3 nut into the nut slot on the condenser arm dovetail
Start to screw the thumbscrew into the nut from the outside of the dovetail
Screw the thumbscrew by hand until it almost touches the dovetail. Do not tighten further at this stage

Step 6: Mount the condenser arm

Slide the condenser arm into the illumination dovetail until it is approximately flush with the top
Tighten the thumbscrew by hand to lock the arm in place.
Do not worry about the exact position, this will be adjusted on first use.

Step 7: Push-fit the LED

Bend the LED cable to 90 degrees from the LED
Push the LED into the top of the condenser
